Modeling for Fabrication
Even as digital design tools have developed, much of our design and construction information is still communicated with paper drawings throughout the industry. With our Digital Practice, we have the ability to deliver detailed model deliverables either as a supplement to or in lieu of traditional 2D deliverables. These models can bring value in a variety of ways: enable schedule compression, provide better cost certainty, or reduce the loss of information when design hands off to construction. Depending on the needs of the projects, they range from advanced bill of materials (ABM) and mill order model to fully connected, “shop drawing ready” models for steel, precast, reinforcing steel, and embeds. The delivery of these services is led by the Construction Engineering group who work on the same platforms as our construction partners, bringing a deep knowledge of structural connections, detailing, and fabrication preferences.
On a current professional sports stadium, Walter P Moore is providing Construction Engineering support to the steel erector. As part of that effort, our team provided a fully-connected TEKLA model and produced steel fabrication drawings for the complex temporary work elements necessary for the erection of the stadium’s roof. This sort of multifaceted modeling for fabrication in support of erection is unique in the industry and has accelerated the fabrication/erection’s team ability to deliver the required temporary structures.
On the Georgia Tech Indoor Practice Facility, our team brought great value to the project by delivering a TEKLA-based BIM directly to the structural steel fabricator to accelerate the production of steel fabrication drawings. Walter P Moore also modeled all of the concrete reinforcing steel in TEKLA and shared this model with the rebar fabricator, who quickly produced a set of bar bend diagrams that were included in the bid documents. This modeling for fabrication reduced the time from start of design to construction completion to just 40 weeks.
